Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are designed to meet the rigorous demands of heavy-duty Ford trucks such as the Excursion, F-250 Super Duty, and F-350 Super Duty. The vented rotor design incorporates pillar-style vanes that improve airflow, helping to maintain optimal operating temperatures during extended braking. The cross-drilled and slotted surface enhances pad bite and helps evacuate brake dust, water, and gases, which can otherwise reduce braking efficiency.

The rotor’s coated hat finish provides corrosion resistance, which is essential for vehicles exposed to harsh environments. With a nominal thickness of 1.181 inches and a discard thickness of 1.102 inches, these rotors offer a balance between durability and performance. The 12.831-inch outside diameter and 3.878-inch overall height ensure proper fitment and compatibility with the specified Ford models. The rotor features eight lug holes on a 6.693-inch bolt circle diameter, matching factory specifications for secure mounting.
